近日，中国正式启动第二阶段6G技术试验，标志着其在下一代通信技术领域的研发进入关键阶段。此次试验由工信部牵头，联合高校、科研机构及通信企业共同推进，重点聚焦太赫兹通信、智能超表面、空天地一体化网络等前沿技术方向。与5G相比，6G将实现更高的传输速率（理论峰值可达1Tbps）、更低的时延（低于0.1毫秒）以及更广的连接密度，为全息通信、数字孪生、沉浸式XR、自动驾驶等未来应用场景提供坚实支撑。第二阶段试验不仅验证关键技术的可行性，还将探索6G网络架构、频谱规划及标准化路径，为2030年左右的商用部署奠定基础。中国此举旨在抢占全球6G技术制高点，强化产业链自主可控能力，并推动数字经济高质量发展。
China has recently launched the second phase of its 6G technology trials, marking a critical step forward in the development of next-generation communication technologies. Led by the Ministry of Industry and Information Technology (MIIT), this phase involves collaboration among universities, research institutes, and telecommunications companies, with a focus on cutting-edge areas such as terahertz communications, intelligent metasurfaces, and integrated space-air-ground networks. Compared to 5G, 6G is expected to deliver significantly higher data rates (theoretical peak up to 1 Tbps), ultra-low latency (below 0.1 milliseconds), and vastly increased connection density—enabling transformative applications like holographic communications, digital twins, immersive extended reality (XR), and autonomous driving. This second-phase trial aims not only to validate core technologies but also to explore 6G network architecture, spectrum allocation strategies, and standardization pathways, laying the groundwork for commercial deployment around 2030. China’s initiative underscores its ambition to lead global 6G innovation, strengthen self-reliance in the tech supply chain, and drive high-quality growth in the digital economy.
